Dave Lanning who posts here as Hammertime is a big user of Nyes. He has had good success with the 582 combo he has been running for a few years now from them. When we travel over to Bunker Hill, IN to race a a good majority of those guys are running Nyes products. I have never seen a bad thing about them posted. I would have no problem dealing with them today if I were to change my motor program.
